Description
Carburetor Polini type PWK 28mm
High quality racing carburetor type PWK.
The carburetor has a turned-out intake tract and intake funnel. Polini deliberately dispenses with the well-known PWK Power-Jet system as this is also a source of faults and is shut down by many PWK users.
This carburetor combines the well-known Polini quality with the outstanding performance of PWK carburetors. All PWK spare parts and jets can be used.

Please note: When installing this type of carburetor, the original intake system can no longer be used, you need a larger intake manifold or a larger intake rubber with a diameter of 35mm. In addition, the original throttle cable, original air filter and the original fuel tap must be replaced by a model without vacuum.
Carburetor for scooters, motorcycles and mopeds
The smooth operation and optimum power output of your scooter, motorcycle or moped depends, among other things, on the carburetor, whose job is to create the right mixture of air and gasoline.
How the carburetor works
When the rider operates the throttle, the carburetor slide moves upwards, increasing the air flow that is sucked in through the air filter. The carburetor then mixes this air with petrol, creating a combustible mixture. This mixture is fed into the cylinder through the intake manifold and the reed valve.
The carburetor is equipped with jets to adjust the ratio of fuel and air and thus ensure an optimum air-fuel ratio. It is important that you adjust the carburetor settings to the setup of your engine.
Adjusting the Carburetor
Proper carburetor adjustment is critical for optimal engine operation and durability. Depending on the type of air filter, cylinder and exhaust of your setup, you will need to readjust main and pilot jets. To check the correct operation of the carburetor, you can refer to the color of the spark plug:
- White spark plug = too lean
- Black spark plug = too rich
- Brown spark plug = optimal setting
